Yo all @Lum @'15 may concern:

Be it known that i, THOMAS J'. deinen, e citizenof the United Sintes,and e resident of St. Cloud, in the connty'of Stearns and State ofMinnesota, here invented new' and useful Improvements in@itching-Biochimie. of which the following is e speciiicetion.

My invention is an improvement in ditch-- ing machines, sind hes for itsobject to pro vide e new and improved machine of the character specifiedwherein tracks nre provided, mounted on suitable Wheels for snpportingand laying'. vvthe seme on opposite lsides oi' the ditch Vto support theditching y machine between. the .seid tracks and Wheels.

In the drawings; Y Figure i is a iront View of the improved ditchingmachine;

Fig'. 2 is n side View of one of the track support laying means;

Figs. 3 and fi are sections on the iines 3- and 4 4; respectiveiy, ofFig. 2, looking in the direction oi the arrows adjacentA the sp'ectivciines;

Fig. .5 is n perspective View of o portion one of the beits; l

Fig. (i is a similar View of one of the supporting Wheels.

In the pre .nt embodiment of the invention, the ditching .machinecomprises n suitable freine i haring a crane 2 to which is connected ascoop or clipper by ineens of the usual supporting beams 4 and cables 5for` operating the said dipper or scoop. The frame l and connected partsere snpportcd at each side of the ditch, as indicated in Fig. i., byanemie of suitable trucks. one ci.: which is shown in detail in Fig. Q.Each of these trucks comprises frame sections 6 and (3a hinged iogethcras indicated at 7, and each truck section carries n superstructure 8 atits inner end and a, bearing 9 at its outer end. each lazaring` loeingsupported oy n snitahie brochet lf). Another bearing 9a is ioni-naief!at the in oer side of each bearing 9 on a bracket 1l, :ind in:ilinemenit with the adjacent hearing S). and a shaft l?, is journalcdin each pair of hearings 9-9"'. Each of these elicits 19 cnrries one ofthe Wheels shown in. Figi. G, and each Wheelv comprises a pair of disks14: arranged in spaced relation and connected by n block 15 which ispoiygonai in cross seetion, being pentagonnl in the present instance.

Each truck 6 end @a carries two pairs oi peripheraiiy grooved Wheels i6,inoifinied upon. sha-:tts 1'? which are journeied heerings .i8 on thetruck. Each pair of whecis is arranged at one end of the truck, and the.

said wheels run upon a suitehle track, to helnter described. which is suoorted in" theV seid Wheels' end the Wheels 14.*115 ieiiore mentioned.

Each of these tracks comprises on end less heit consistingof av seriesci. links 19 f'w'neh are p1votoiiy;eo1 iiiected at their ends.l

es indicated et E20, endit will be noted that euch link consists of twosections which. are

clizinnei shaped and eimnged with their channeis outward, the seidsections being secured together in any snitebie or desirable manner. Thebelts are supported hy the wheels lie-15, end by the wheels i6, theietter- Wheels running upon the heit as it is inid by the ditchingmachine in its progress.

Rails or ties 9,1 are secured transversely oit the endless heits in anysuitabie mannen the (centers of the ties being; .at the beit, and itwill be noted in Figs. 3 and 5 that one Well of each of the channelshaped sections.

oi the links is of greater depth than the other. These Wheels areontwarm end tney run nnen the disks ifi oi' the wheels o.

and upon the iinnges of the Wheels 1G. The

joint i' before inentionezfi permits a iilnited movement o1" the trucksections with respect to each other, and the said connection or joint isifornicd` as shown in Fig. 4, by." means of plates :24: secured to the'opposite `iiaces of the sections. the seid piates extending 'Beyond theadjacent ends of the sections and being pirotally connected at 7.
